does code::blocks reserve names other than c++ keywords?

霸气de小男生 提交于 2019-12-10 15:41:40
问题 I am new to code::blocks and quite unexperienced in c++ as well. I know there are many keywords, that I am not supposed to use for variable names and they are usually displayed in a different color, as they are in visualstudio. Now when I was copying some code fragments over from my old vs project to a new code::blocks project, some of my variable names suddenly got colored. For example in this code the variables begin and end are displayed in green now, and I don't understand why. int begin

CodeBlocks C++ Bug

天大地大妈咪最大 提交于 2019-12-10 11:57:18
问题 I was doing something in C++ (CodeBlocks), but I found a weird problem. I sent my code to my friend (he tested it in DevC++) and it worked. I tried these two codes: #include <iostream> #include <math.h> using namespace std; int main() //this function works { if (pow(3, 2) + pow(4, 2) == pow(5, 2)) { cout << "Works" << endl; } else { cout << "Nope" << endl; } } But, then I changed the main function like this (and it didn't work): int main() //this function doesn't work { int t1 = 3, t2 = 4, t3

Code::Blocks C++ compiling with MacOS Mojave : fatal error: sys/cdefs.h: No such file or directory

问题 (This is my first question ever on StackOverflow) I have to use a Mac at work, and I'm coding in C++ with Code::Blocks (because I am used to this IDE). 2 days ago I upgraded from MacOS High Sierra to MacOS Mojave and I can fairly say that... it was a bad decision. Now, when trying to #include <math.h> I get this error : fatal error: sys/cdefs.h: No such file or directory . I have tried to reinstall the xcode line command tools with xcode-select --install , but it still doesn't work. Does

问题 This question already has answers here : What is an undefined reference/unresolved external symbol error and how do I fix it? (32 answers) Closed 2 years ago . I am experiencing something weird with my c++ source file or perhaps the compiler itself. It seems that when I attempt to compile the file, it hits me with a message - undefined reference to "Basic_int_stack::Basic_int_stack() undefined reference to "Basic_int_stack::Push(int) Here is my code (I'm still a beginner so don't expect any

codeblocks, single project, many executables

☆樱花仙子☆ 提交于 2019-12-10 05:48:04
问题 I use Code::Blocks and C++ . My project should build multiple executables (set of small tools that use shared libraries). How to set up CB to generate multiple binaries, each with its own main() ? 回答1: Take a look into CodeBlock's manuel, specifically chapter 1.8, where it has this workspace example : A project A contains fundamental functions which are made available to other projects in the form of a library. Now, if the sources of this project are modified, then the library has to be
